SAFE SHUTDOWN ANALYSIS REVEALS NONCOMPLIANCE FOR A FIRE OUTSIDE DIESEL ROOM
"During the performance of a focused area self assessment (FASA) for the Clinton Power Station Fire Protection Program, the FASA team identified a noncompliance with the Safe Shutdown Analysis for a fire outside the Diesel Generator (DG) rooms (i.e., Fire Zone CB-1e, CB-1f, CB-2 and CB-4). The CO2 panels for each DG train are all located in the same area outside the DG engine bay rooms (i.e., 737' Control Building) and a fire in this area could cause fire damage to all three CO2 panels and/or wiring such that a trip (short) could be initiated to all three DG Ventilation (VD) fans. Loss of the VD fans (1VD01CA, B and C) results in loss of cooling in the DG rooms and ultimately loss of the diesels. This constitutes an Unanalyzed Condition that Significantly Affects Plant Safety.
"Compensatory measures are in-place that will allow these VD trips to be overridden and the VD fans to be restarted from the Main Control Room.
"The NRC Resident Inspector has been notified."

POTENTIAL DESIGN BASIS FLOODING ISSUES RELATED TO BATTERY ROOM WALL PENETRATIONS AND CABLE VAULT FLOOR DRAINS
"On 9/20/2013 at 1600 EDT, R.E. Ginna Nuclear Power Plant determined that there was a potential for flooding of both battery rooms during a design basis flood due to unqualified wall penetration material and partially blocked cable vault floor drains. Testing of underground cable vault drain lines failed to demonstrate that they could pass the required flow due to debris accumulation. The penetrations are below grade and approximately five feet above the bottom of the vault floor. During a design basis flood, water could flow through the holes in the vault manhole covers and fill up the vaults to the level of the penetrations. Since the penetration barriers do not appear to be qualified for flooding, leakage into Battery Room B could be expected. Battery Room A and Battery Room B have a normally closed emergency fire door between them that allows water to pass under the door into Battery Room A where a sump pump exists. It is not currently known if the sump pump capacity would have been able to mitigate flooding of both battery rooms. The discovery of this condition is being reported as an unanalyzed condition as defined by 10 CFR 50.72(b)(3)(ii)(B).
"The 125VDC system is currently Operable. Current weather forecasts do not predict the conditions necessary for flooding. Additionally, compensatory measures have been implemented to provide barriers to water entry into the vault manholes until corrective actions are implemented.

AGREEMENT STATE REPORT - MISSING MOISTURE DENSITY GAUGE
The following report was received from the State of Texas via email:
"On September 25, 2013, the Agency [Texas Department of State Health Services] was notified by a licensee that one of its Humboldt Model 5001EZ moisture/density gauges was missing and presumed stolen from its facility. The gauge (SN: 3561) contains one 10 millicurie cesium-137 source and one 40 millicurie americium-241/beryllium source. The gauge could not be located on Friday, September 20, 2013, and the licensee began a search and investigation. On Monday, September 23, 2013, it made the determination that it was missing/presumed stolen. The gauge had been secured inside a locked storage area inside the facility with the licensee's other gauges. No other gauges were missing. The licensee notified local law enforcement and a gauge sales/service company in Houston. The Agency will notify the Texas Pawnbrokers Association. An investigation into this event is ongoing. Further information will be provided as it is obtained in accordance with SA-300.
"[The] Houston Police Department [was notified by the licensee on 09/23/2013]."
Texas Report # I 9118
* * * UPDATE AT 1540 EDT ON 4/27/2016 FROM ARTHUR TUCKER TO MARK ABRAMOVITZ * * *
The following report was received via e-mail:
"On April 26, 2016, the Agency was notified by the licensee they had recovered the gauge reported stolen on September 23, 2013. The licensee reported they were contacted by the Houston, Texas Police Department (HPD) and informed that HPD was in possession of their missing gauge. The HPD stated they had recovered the gauge from a vacant property and they had been storing it in their impound building for about one year while they searched for the owner. The licensee will leak test, calibrate, and inspect the gauge prior to returning it to service."
Notified the R4DO (Groom), ILTAB (Rockhill via e-mail), Mexico (via e-mail), and NMSS Events Resource (via e-mail).
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AUXILIARY BUILDING SPECIAL PARTICULATE IODINE NOBLE GAS (SPING) MAINTENANCE
"On September 20th, 2013 at approximately 0645CDT, the Kewaunee Power Station rendered the Auxiliary Building Special Particulate Iodine Noble Gas 'SPING' both Mid and High Range [radiation monitors] non-functional for maintenance on the Mid range. The Emergency Response Organization (ERO) team has been notified of the Auxiliary Building SPING non-functionality due to the maintenance.
"The SPING is expected to be out of service for approximately 7 hours.
"This condition is being reported in accordance with 10CFR50.72(b)(3)(xiii) as an event that results in a major loss of emergency assessment capability (unable to sufficiently identify and classify an Emergency Action Level for offsite radiation conditions).
"The NRC Resident Inspector has been notified."
* * * UPDATE FROM DANIEL BACKUS TO CHARLES TEAL AT 1453 EDT ON 9/20/13 * * *
The maintenance required the replacement of the Geiger Muller (GM) detector. The GM detector requires a 12-hour burn in time. The detector is expected to be returned to service at approximately 1900 CDT on 9/21/13.

PART 21 ISSUE ON ROSEMOUNT MODEL 710DU TRIP UNITS
The following is a summary of the information received from Rosemount Nuclear Instruments, Inc. (RNII) via facsimile:
In August 2013, Rosemount conducted normal, transient and accident radiation testing on a sample of Model 710DU Trip Units (master and slave) to verify radiation performance of some commercial grade semiconductor components. The results indicated that post-exposure radiation performance may not meet the criteria established in their previously published Qualification Report D8200037. This affects all transmitters shipped from RNII since June 1983.
Per RNII's Model 710 Trip/Calibration System Discontinuance Letter dated September 14, 2011, RNII stopped accepting purchase orders as of December 31, 2012. At this time RNII is no longer accepting orders and no corrective actions are being taken.
These transmitters were purchased by:
Carolina Power and Light/Duke Energy, Commonwealth Edison Co., Constellation Energy Group, Inc., DTE Energy Services, Inc., Energy Northwest, Entergy Nuclear, LLC, Exelon Generation Co., LLC, Gavial, General Physics Corp., GE Nuclear Energy, Georgia Power Co./Southern Nuclear Operating Co., Harlo Corp., Knolls Atomic Power Lab, Long Island Lighting Co., Mercury Co. of Norwood, Inc., Mississippi Power & Light Co., Nebraska Public Power District, NextEra Energy/FPL Energy, Northern States Power/XCEL Energy, Inc., NuTherm International, Inc., PPL Susquehanna, LLC, Progress Energy Carolinas, LLC/Duke Energy, PSEG Nuclear, LLC, Public Service Electric & Gas, Singer Co., Tennessee Valley Authority, Texas Municipal Power Agency, United Controls and Westinghouse Electric Corporation.
